Fusion 17

I'm at the FUSION17 conference in Hobart, Tasmania.  At the beginning of today's session I tweeted, using the hashtag #fusion17 not realising that it had already been used by a party being organised in Texas this spring break (see attached picture).  Oh well.

The conference is one of a series which has been going for 20 years to bring together people working on nuclear reaction mechanisms which lead to fusion.  That's a somewhat minor part of what I do, though what I do doesn't really fall within any one specialist conference series, so it's about as on-topic as most conferences I ever go to.  The fact that I know quite a few of the people here is probably a sign that I belong sufficiently well enough to attend.  

We're about half way through day one, and as usual, the conference talks have filled me with enthusiasm for the research area, and given me lots of ideas of calculations to perform.  I was also pleased and somewhat embarrassed to see my name in the talk by Michael Thoennessen in which he listed the names of all attendees at the conference who were co-authors on papers which announced the discovery of new isotopes.  I have 4 written next to my name, apparently being a co-discoverer of four isotopes.  I can't claim to have been on the experiment(s) leading to these discoveries, but I was involved enough in some of the calculations associated with them to be on the discovery papers.

Erasmus Joint Master Degree in Nuclear Physics

If any readers are looking for opportunities to study for a funded master's degree in nuclear physics, an email I received earlier this week might just have what you are after.  It's a 2-year taught master's degree course entitled (deep breath) Erasmus Mundus Joint Master Degree in Nuclear Physics (EMJMDNP).  The email says that "the course is supported by EACEA Agency of European Union with full scholarships (including travel costs and health insurance)"

The degree is co-taught across several universities across Europe, and from what I can see all students will spend some time in each of Spain, France, and Italy.  It looks pretty interesting, and well worth considering as a next step if you have just finished your bachelor's degree and nuclear physics takes your fancy.  Tell them I sent you :-)

UK Leaving Euratom. What does it mean?

According to official explanatory notes accompanying the European Union (Notification of Withdrawal) Bill, the withdrawal of the UK from the EU will mean withdrawal from the Euratom programme.  

As an academic nuclear physicist, my knowledge of Euratom comes from its role within the European research mechanism.  The Euratom page at the European Commission website says that "Euratom is a complementary research programme for nuclear research and training" and goes on to describe its role in research into decarbonisation, nuclear fission research, nuclear waste management, fusion energy, and radiation protection.  Its most high–profile project is the ITER fusion reaction; the International Thermonuclear Experimental Reactor, based in France, to which Euratom contributes, with other partners.

But as well as being a scientific research programme, Euratom is also a very high-level treaty that the UK has just confirmed it will leave at the same time as it leaves the EU.  What I have not seen anything about is whether and how the UK will step in to replace the funding of research in these areas.  Will we re-join ITER as an independent partner?  What about pursuing the other goals of the Euratom research project for UK scientists?  Will they have increased funding via the UK Research Councils to replace Euratom?  The UK Government need to state the position on the wider consequences of departure from Euratom, if they wish to inspire confidence to the UK scientific community in the management of the Brexit process.

Buy Lego. Save the world.

A friend of mine who works at Surrey Satellite Technologies Limited alerted me to this pretty neat thing:  Lego has a scheme whereby proposed kits and designs can be produced by them if they receive enough support on a community website.  Someone has proposed a kit for the Galileo Global Navigation Satellites, parts of which are made here in Guildford.  If you'd like to see the kit made available, please add your support at the Lego Galileo Spacecraft page.  It doesn't oblige you to buy one when it gets to market, but Lego is pretty cool stuff, and Lego are also a place where at least I feel comfortable spending my money, given that every time we spend money we are undertaking an act about as political as anything else we do.

Applications of Nuclear Physics

A really nice and extensive article on many of the uses of nuclear physics appeared on the arXiv this week, written by Anna Hayes of Los Alamos Lab.  As well as including the most obvious applications (weapons and power) and perhaps the most widespread, as well as the first, application (medical), it also covers some of the neat uses in areas like geology, where the study of isotopic abundances in things such as groundwater can tell you what it going on far underground.  I've yet to read the whole thing yet, but it looks definitely worth bookmarking as a go-to piece whenever you are looking to discuss the range of things nuclear physics is applied to.

The figure attached to this post is from the paper, showing some of the ancient (pre-historic) natural nuclear fission reactors that existed in what is now Gabon, detected by the unusual isotope ratio of the remaining uranium, as well as some fission products.  See Anna's paper for more details!

Hamish, dob 17/12/2016 <3

I'd like to present the results of a recent fusion-fission reaction.  One event was detected, on Saturday morning, with the final product observed to have a mass of 2.45 × 1030 MeV/c2. As a working name, we have have assigned Hamish, though obviously it needs to be ratified by the appropriate authority, via the Guildford Register Office.

The initial reaction products are remarkably more or less as they were before the reaction, though some evidence of decay seems to have taken place.  The results of previous successful experiments (codenamed Flora and Alba) are both delighted about this new emanation.

More new isotopes

I posted not so very long ago about the announcement of the discovery of a hitherto unobserved isotope of lead.  The same laboratory has now had the announcement published about the observation of two further new isotopes; 240Es (Einsteinium, element number 99) and 236Bk (Berkelium, element number 97)

Congratulations to the team, drawn from the home institution of the laboratory, Jyväskylä University, as well as from collaborating institutions around the world.

If you want to read the research paper, it is published as an open access paper (i.e. anyone can read it without a subscription to the journal) here.  The publication date of the journal issue in which the paper features is in 2017, strangely.
